Vulnerability Data

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could write dispatch metadata to an arbitrary location on the host by supplying a crafted search identifier to…

more

a Representational State Transfer (REST) API endpoint and affect system integrity on the host. The vulnerability is possible because Splunk Enterprise does not validate the search identifier before using it to create a dispatch directory. For more information see About configuring role-based user access (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.2/manage-splunk-platform-users-and-roles/about-configuring-role-based-user-access) in the Splunk documentation.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Input validation directly stops untrusted pathnames containing ../ sequences from being used to construct traversals outside the intended directory.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input validation and path sanitization that prevent directory traversal flaws.

ID.RA-01 partial match
prevents

Vulnerability identification processes will discover path traversal weaknesses during code or configuration review.

PR.AA-05 partial match
prevents

Least-privilege file permissions and access enforcement can limit the damage from a successful traversal.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Secure coding standards require neutralizing '../' sequences and using safe file APIs, eliminating this exact weakness.

finds

Security testing in development catches path-traversal flaws before release but does not itself implement the control.

prevents

Secure development lifecycle mandates input validation and path sanitization that directly prevents directory traversal.

prevents

Application security requirements include explicit rules for safe file-path handling and canonicalization.

prevents

Secure architecture principles discourage unsafe path construction but do not prescribe the specific coding fix.

mitigates

Information access restriction can limit which files are reachable, reducing impact but not preventing the traversal vector.
